A rare close flyby of a comet near Mars put NASA's orbiters in a potentially dangerous situation, but also allowed them to study the moving space object.
A gorgeous pic snapped by Cassini shows the outer rings of Saturn in crisp detail, with ice moon Tethys bringing up the rear.
The discovery of a new unusually bright dead star leads astronomers to question assumptions about a type of cosmic radiation -- and pulsars themselves.
Researchers from three different labs have created FlexSense, a surface with embedded sensors that makes for some pretty incredible applications. We don't know when this concept might show up in commercial products, but we're already looking forward to it; don't miss the demo on today's show.
NASA is preparing the new Orion spacecraft for a first test flight. Your name can fly along with it -- eventually to the Red Planet.
